CAN-HEADING' MACHINE.

SPECIFICATION forming part of Letters Patent No. 321,263, dated June 30, 1885.

Application filed July 21, 1884. (No model.)

T aZZ whom it may concern.-

Be it known that l, FRANCIS A. WALSH, of Milwaukee, in the county of Milwaukee, and in the State of \Visconsin, have invented certain new and useful Improvements in Oan Heading Machines; and I do hereby declare that the following is a full, clear, and exact description thereof. I

Hy invention relates to improvements in machines for heading, beading, and closing cans, and will be fully described hereinafter.

In the drawings, Figure 1 is a side elevation of my improved device. Fig. 2 is a like view on the opposite side of the same. Fig. 3 is a top view of the machine. Fig. 4 is a horizontal section on line 00 m of Fig. 1, showing the mechanism by means of which the revolving table is operated. Fig. 5 is avertical sectionshowing a can in position between the forming-head andthesupporting-chuck. Fig. 6 is an under side view of the forming-head. Fig. 7 is a vertical central sectionshowing a can in position while being finished. Fig. 8 is an elevation of the mandrel and chucks. Fig. 9 is avertical section showing the holder used in heading cans and themanner of its attachment to the revolving table. Fig. 10 is a top view of the same. Fig. 11 is a vertical section showing the construction of the heading-shaft. Fig. 12 is a detail. Fig. 13 is a broken elevation of the device used to give the intermittent motion to the revolving table.

Fig. 14. is a top view of the worm-wheel driving the said device, and Fig. 15is a like View of the clasping-head.

A is the stand of my machine, which is firmly bolted to a suitable base, and in one side of this stand, near its base, one end of a driving-shaft, a, has a bearing, while its other end has a bearing in a standard, A". The shaft a carries the driving-pulleys, and these are belted to like pulleys, a, on a shaft, of, that is journaled in the upper portion of the stand A, a branch of which, A forms a bearing for its outer end, while its inner portions have bearings in the standard at a a. (See Fig. 1.)

Between the bearings a a the shaft has a worm-wheel, (r, keyed to it, and on its end opposite the pulleys a the shaft (6 also carries a bevel-wheel, a, which latter meshes with another beveled wheel, I), that is keyed onto a shaft, 1), so that the shaft may slide up and down in its hub. A rounded head, If, is screwed on the upper end of shaft 1), and is held in adjustment by a set-screw. A collar, 1), is fastened onto the shaft by a set-screw, and between the collar and the wheel bis coiled aspring, b the resilient action of which serves to keep the upper end of the shaft 1) up against the concave bearing end of the arm B. This arm B is suitably hinged in the upper end of the stand, and its said end is connected by a loosejoint with the upper end of the post B fastened in the yoke D. This yoke is vertically perforated to fit and slide up and down over the upper ends of the shafts E and E, suitably journaled in the stand A.

Keyed onto the shaft E is a worm-wheel, F, which meshes with another worm-wheel, a", on shaft a". Supported on the upper face of the wheel F, and having its bearing on the shaft E, is the cam-wheel F. This latter is provided with a spring-clutch, f, suitably mounted in its cup-shaped upper face, and which is adapted to take in either one of the sockets ff cut into the upper face of the worm-wheel F, as the inner end of the lever G, suitably fulcrumecl in the stand A, is raised against its spring g, to free the clutch by pressing downward on the handle G. The wheel F has two cam-projections, f f formedin its upper face, and these projections are designed to come in contact at every revolution of said wheel with an anti-friction roller, cl, suitably mounted 011 the lower face of the yoke B. This is raised accordingly, and with it the rear end of the lever B. The opposite end of this latter is depressed against the upper end of the shaft b, which is lowered thereby against its spring b and with the former B, fastened on the lower end of the same.

Projecting on the lower rim of the wheel F, midway between the cam projections f 2 f 2 are, the cams f f, and these are designed to alternately come in contact with the anti-friction roll 6, suitably mounted in the bifurcated upper end of the arm 6, fastened onto the shaft or rod E. This latter,which is fitted to slide in bearings of the stand at e e, is rigidly connected toward its lower end to a sleeved bar, e, the opposite end of which is suitably connected to the vertical rod 0*. A coiled spring, c fitted over said rod between the bar 6 and the portion of the bracket A through which said rod slides, serves to hold the same up in either one of the perforations h h of the revolving table H when the shaft 12 is depressed with the former B. The tableis thus held firmly in place with the can as the former is rotated around it. As soon as this latter has returned to its normal position with its spring b the anti-friction roller 6 passes on under one of the cams f 3 f and the rod E is depressed, lowering the rod 6 against its spring 0 and leaving the revolving table unlocked. As soon as thisis produced,and before the anti-frictionroller cl comes in con tact with the other cam'f", another anti-friction roller, 6, mounted on each end of the doublearm E, fastened onto the rod or shaft E, comes in contact also with an arm,e suitably mounted on the shaft J. Thislatter has its bearingsin convenient portions of the standA, and carries an arm, j, to which is suitably attached the U shaped piece j. Hinged between the ends of this piece is the leverj the opposite end of which is loosely held between the upper and lower plates of the pawl-carrier H, suitably mounted with the ratchet-wheel h on shaft H", in the upper end of which the revolving tableH is fastened. A spring-pawhh, is pivoted between the said plates,so as to take into the teeth of the ratchet. As either one of the anti-friction rollers e e strikes the arm 6, the ratchet is rotated one step with the table Hand the shaft H Aspring, fione end of which is attached to the lever 9' while the other endis fastened to the bracket A of the stand A, serves to bring the arm back in its normal position and to carry the carrier H rearward, to allow of the pawl h coming into engagement with a new tooth of the ratchet.

L indicates a can-holder or chuck. The stem 1. of this chuck is received in either one of the perforations h h h of revolving table H. After being passed through the center of the bottom chuck, L, thelower end of the stem Z is squared to fit in the socketed upper end of theloekingrod e. The bottom chuck,L,is providedwith the dowel-pins Z Z, which project downward from its lower face, in line with the outer edge of the table H, and will prevent said chuck from turning on the stem l. The upper face is grooved at l to receive the lower edge of the can M, and a semicircular notch,P,is cut at a suitable point in the outer edge of its lower face, as shown in Figs. 5, 7, and 8.

Secured to or forming part of the bracket A isa frame, P, having an arm, p, which is slotted to receive the wrist of the arm 0, on the end of which is suitably mounted the curving-former O. Arock-shaft, P, is journaled in rearing-boxes p p, which are adjustable in the slotted edges of the frame B by means of the bolts 19 19 This rock-shaftis connect-ed through its crank 19 to the lower end of the rod Q, the upper end of which is loosely attached to the side'of the yoke D, described above.

Fastened onto the free end of the rock-shaft P is the arm 1), which is screw-threaded in most of its length to support between adjustable fastening-nuts the beading-former P The rock-shaft has also the short arm p keyed onto it opposite the arm 0, and designed to raise this latter, with the former 0, against the can-edge by the same motion which will bring the arm 1) up against the side of the can.

As the beading and curving obtained by means of the respective formers O and P necessitate the revolving of the canchuck, I provide for that purpose a clasping-head. C, the construction of which is detailed in Fig. 7. This clasping-head may be used either in place of the forming-head B, or may be mounted on a separate shaft, 0, as shown in Fig. 2. This shaft is mounted parallel with B. The upper end of the shaft 0 is screwthreaded to receive the nut 0 against the under side of which bears the ring or collar 0. The outer faces of this collar are hollowed at diametrically-opposite points, to receive the bearing ends of the screw-bolts c 0 working in the bifurcated ends of the lever 0 This lever is suitably slotted at about its center to receive the upper end of an arm, 0*, projecting from the stand A, and on which it is hinged. The inner end of the said lever 0* is connected loosely to the upper end of the post fastened in the yoke D close to the post B", being moved simultaneously with this latter through the cam-wheel F, described above. The motion thus imparted to the le' ver 0 is transmitted to the vertical shaft 0 through the spring c,coiled around said shaft between the loose collar 0*, bearing against the lower face of the nut 0 and the collar 0 fastened to the said shaft a slightly above the bearing 0 end of the shaft 0, a top View of which is shown in Fig. 15, is provided with the central movable plate, 0 in the upper face of which are the bifurcated studs 0. In the upper ends of these latter are hinged the inner ends of the bell-crank levers 0 c,fulcrumed in the arms 0 c of thehead. A spring,c, suitably mounted between the upper face of the central plate, ciand the arms 0 0, serves to depress the plate downward, and keep the free ends of the bell-crank levers 0" c outward, so that when the clasping-head C is brought down against the upper end of the can, the movable central plate being forced up against the springs, the edges of the can are tightly clasped bythe levers.

The forminghead B, carried on the screwthreaded lower end of the shaft b, is fitted to receive in its suitably-socketed outer rim: the heading-formers b b, mounted on the headed.- stems I) h fastened in said head by the set screws 12 1)". A flange, If", is formed around the outer lower edge of the said forming-head B, and the inner face of this flange is shaped so as to fit squarely, or nearly so, against the can-edge, which is received in the bottom of the groove 1) cut in the lower face of the same, inside of the flange b. As the strain of the formers b b when revolving around the edge of the can has a tendency to turn this latter on its chuck, I provide the flat Spring b (shown in dotted lines in Figs. 1 and 2,) and mounted in any suitable manner on the rock-shaft P, the motion of which, through its connection with the yoke D, is coincident with that of the forming-head against the can, and, as it presses against the periphery of the said can, keeps it from turning with the forming-head.

In Figs. 9 and 10 is shown on an enlarged scale the device I have designed to support cans-when being headed or closed after filling. This device consists of the semicircular supports R R, 'by means of which the can is firmly embraced below the upper head or ofiset formed to receive the edges of the cover or head, and against which the upper edges of both can and cover are curved down together. In order to adapt the revolvingtable for use with these semicircular supports, its outer rim is notched from the center of the perforations h 12, wherein the stem of the canchuck is received for ordinary work, the pieces k h being held in position in the notches, in this case by means of the screwbolts h h In either one of these notches h h is received the semicircular support R, which is bolted onto the segmental flange r of the fastening-piece r. This last is in turn firmly held in place by a bolt, 1", screwing in end of the arm R which in turn is fastened in any suitable manner to the rock-shaft P, described above, and in place of the spring 0". These semicircular supports may also be used when it is desirable to put in both heads of the can at once, and when these are used I dispense with the locking-bolt 6*, or adjust it on some other part of the machine, and for it substitute a similar shaft to b, with a similar forming-head and connections with the driving mechanism.
